PRT 140: Lesson 6 Flow Measurement – Mining Mill Operator ...
Net vs. Gross Flow — LIQUID (also applies to total volume) Gross Flow = volumetric flow rate at actual conditions ('observed') — what most flow instruments measure. Net Flow = volumetric flow rate converted to flow rate at standard conditions — usually 60 deg F. WHY NET? To keep consistent — measure flow at -20 deg F, then product heats up to 40 deg F — different observed amount ...
